Not being able to have multi-DPI in X is what moved me over. Scaling one display makes everything fuzzy and increased my idle load substantially, though maybe a different compositor might have given different results.

EDIT: I should also mention that my experience is overall positive, I use swaywm so config and setup is easier than with X (no xorg.conf to tinker with every driver update) with a small stability tradeoff. Sometimes sessions will crash out when doing things with the GPU dmabuffers, which for a lot of people isn't really acceptable, but also who's usually using dmabuffers?

Oh and mouse interactions can be really wrong when going between xwayland windows and native ones.
